Abstract

An adjustable air conditioning and regulation apparatus for human respiratory system includes an air treatment assembly and a host controlling assembly. The air treatment assembly has an air filter, a humidity control, a heating device for temperature control and a pressure control. The air filter removes the particles and smells from the air. The clean air is regulated by the controls that maintain the clean air at a desired level of temperature, pressure and humidity. The apparatus provides clean, fresh and comfortable air for the patients with compromised respiratory system.
